Simply put, mindfulness is when we pay attention to what is happening in the present moment, without judgment. Much of the time, most of us are caught up in doing, as opposed to simply being, or we are trying to hang onto something we expereince as pleasant or get away from something that we experince as unpleasant. Developing our ability to be mindful, allows us to become more aware our true needs and wants (which improves our ability of getting these needs and wants met) and to expand our tolerance or acceptance of things that we cannot change. One way of developing mindfulness is through meditation practice.
This short video provides a light-hearted presentation of how meditation can be incorporated into your daily life.
